The introduction of zebra mussels in the Great Lakes is an example of which type of release? The introduction of zebra mussels in the Great Lakes is an example of release.

The zebra mussel known biologically as Dreissera Polymorph's, is a small freshwater mussel which its species was originally from the lakes in Southern Russia and Ukraine. Known globally as invasive species, they got their name through the striped pattern which are mostly seen on their shells.

Zebra mussels were noticed in Canada in the Great Lakes in 1988 at lake St. Clair. They were believed to be unintentionally released into the lakes in the ballast water of ships going to oceans, traveling the St. Lawrence Seaway. Another belief was linked to the introduction or release through anchors and chains even though this belief has been described as mere speculation.

it has been deduced that larval mussels was released to the Great Lakes during the ballast exchange of a cargo ship from the Black Sea. so it is an example of un-intentional release.
